Munich, Germany – 02 June 2026 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduces silicon carbide (SiC) bidirectional switches (BDS) built on rugged 750 V CoolSiC™ G2 technology. A vertically integrated dual-die with common drain design in a top-side-cooled Q-DPAK package integrates two power switches into one for simplifying design and enable revolution of legacy topologies. The 750V CoolSiC BDS delivers reliability margin what modern grids and energy systems demand resulting lowest Total Cost of Ownership during the application lifetime.

The 750 V CoolSiC BDS offers best-in-class R DS(on) x Q fr, superior R DS(on) x Q OSS, and low Q g, reducing switching and conduction losses for ultra-fast, efficient switching. A V GS(th),typ of 4.5 V at 25 °C paired with an ultra-low Q GD/Q GS ratio enhances immunity to parasitic turn-on, while extended gate-bias tolerance of −11 V to 25 V transient voltage increases design margin and compatibility. Rated at 200 V/ns dv/dt, these devices support high-frequency designs without compromising durability. The product portfolio will start from 14 mΩ, up to 66 mΩ.

Engineered for demanding power systems, the 750 V CoolSiC BDS delivers 840 V (BR)DSS with superior margin for bus voltages above 500 V, proven avalanche resilience, overload endurance up to 200 °C for 100 hours, and 2 µs short-circuit withstand time. These devices safeguard systems from real-world voltage surges, energy pulses, transient stress, and inrush current – delivering durable, fault-tolerant operation.

The 750 V CoolSiC BDS expands Infineon's Top-Side Cooled family, enabling native liquid cooling in today's most demanding and rapidly evolving applications. New energy efficiency levels became possible with new design iteration on topology level.

In automotive applications the devices are ideal for on-board chargers (OBCs) and EV charging as well as eFuse and pre-charge circuits. Paired with CoolSiC H-DPAK half-bridge, it enables a smooth transition to the single-stage OBC based on SiC technology, delivering high power-dense, space- and cost- efficient designs.

In industrial applications, it brings revolutions with rapidly evolving use cases:

• HVDC AI PSU with native liquid cooling
• Residential Solar and Storage
• HVAC for hospitals and onsite data centers
• CSI Drive for eVTOL
• HVDC protection in power and IT rack
• Humanoid fleet fast charging
